Article here. “The book was published by the Center for Digital Content of the National Security Agency, and is filled with advice for using search engines, the Internet Archive and other online tools.”

Lest you think that none of this is new, that Johnny Long has been talking about this for years at hacker conferences and in his book Google Hacking, you’d be right.

“Lest” makes no sense there; they want “If” or “In case” (and “you’re” would be better than “you’d be").
